EXTENSION-TABLE.

SPECIFICATION forming part of Letters Patent No. 401,310, dated April 9, 1889.

Application filed April 27, 1888.

To all whom it may concern.-

Be it known that we, ERNST H. \V. STAHL- HUTH and HENRY W. STAHLHUTH, citizens of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Extensi0n-'lables; and we do Cexlare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

The special object of the invention is to always keep the inner leaves of an extensiontable on the frame, so that they may be used without loss of time; secondly, to extend the table-frame itself, so as to give the leaves, with their superposed weight, a firm and substantial support; thirdly, to make both the end leaves slide, so as to contribute to the extension, and, fourthly, to arrange the eX- tcnsion-leaves under the end leaves, so that they may be elevated into place when need ed.

Figure 1 of the drawings is a bot-tom plan view of table without the leaves; Fig. 2, a longitudinal vertical elevation, partly in section of Fig. 1 Fig. 3, a similar view on line 1 y of Fig. 1; Fig. 4,21 side elevation showing the. extension-leaves one under the other; Figs. 5 and 6, detail views hereinafter described. Fig. '7 is a perspective view with all the leaves removed except the end ones. S is a perspective view showing the stepwedgcs and the guide-pieces on one of the leaves.

In the drawings we show the table-frame, consisting of the two sectionsAB, connected by a dovetailed groove and tenon, a b, so that they may be drawn out in opposite directions, each being provided with two legs, a a and h I). The section A has on top the dovetailed tenons a? a on which fit the dovetailed grooves c c, which are on the under side of the leaf 0, said grooves run- Serial No. 272,039. (No model.)

ning to alip, 13, in which are caught the under hooks, D l), which are attached to the under side of the leaf O just outside of the frame, so that the next leaf 0 may be prcvented from sliding out on either side.

The leaf 0', when pushed as far as possible on the table-frame, is not only supported on the legs and frame, but also upon standards E E, which may be pivoted and upheld by springs, so as not to create too much friction when the end leaf, 0, is slid back and forth. It also rests. upon the inner end of a riser, G, so that the table will be solid and the leaves not liable to yield under weight.

The leaf 0 is provided 011 its underside with the fixed wedges H H, corresponding to the wedgesl I, which are rabbeted and slide upon rails J J, attached to the inside of the side rails of the frame. Each of the movable wedges I is flexibly connected with one end of the T-head of the lever K, which is fulcrumed upon a cross-bar, L, on the bottom of frame A. The leaf C- has also on its bottom the guide-pieces M M, which work up and down in the vertical-frame grooves a The leaf C has on the under side the dovetailed grooves c o working on the corresponding tenons, a" a, of the frame, so as to allow of extension. lVhen the leaves 0 C are sufficient for table use without the extcnsiondeaves C 0 the latter lie in the side-frame grooves A A but if one or both of the latter are required the leaf 0 is raised by the wed I I, which slide under the wedges H H. By moving the T-lever to one side the wedges are pressed against each other to raise leaf C and by moving it in an opposite direction the wedges are forced apart, so as to lower said leaf. The leaves are thusall retained in the table, may be easily raised into place, and require but little expenditure of labor or waste of time.

What we claim as new, and desire to protect by Letters Patent, is-

1. An extension -table having two dovetailed tenons, (L 011 one of its two sections, a correspondingly-grooved leaf, 0, with the lip c, a leaf, G with subjaeent hooks D, standards E, and riser G, arranged as shown and described, for the purpose set forth.

2. In extension-tables, the lever K and movable Wedges I, the latter flexibly connected with one end of the T-head of said lever, in combination with Wedges II II and leaf G", as and for the purpose specified.

In testimony whereof We affix our signasores in presence of two witnesses.
